ALCOHOL-LAMP.

SPECIFICATION forming part ofv Letters Patent No. 615,586, datedDecember 6, 1,898.

Application filed August 1, 1 8 9 8.

To all whom it may concern:

Beit known that I, GILBERT T. SUTTERLEY, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Alcohol-Lamps, of which the following is aspecilication.

My invention consists of certain improvements in the alcohol-lampforming the subject of Alexander Stewarts application for Letters Patentiiled March 24, 1898, Serial No. 675,012, one object of my presentinvention being to effect the diminution or extinguishment of the iiamewithout tilting the lamp-fount to as great an extent as is necessary inthe previous construction or in some cases without tilting the fount atall, and a further object of the invention being to provide means forpreventing the evaporation of the alcohol when the lamp is not in use,such means being also, by preference, available as a measuring andfilling device whereby alcohol may be supplied to the absorbent contentsofthe lamp-forint. These objects I attain in the manner hereinafter setforth, reference being had to the accompanying draw-V ings, in which--Figure l is a transverse section of an alcohollamp constructed inaccordance with my invention, showing the parts in the position whichthey assume when the lamp is burning with a full flame. Fig. 2 is asimilar view showing the parts in the position assumed when the lamp isburning with a diminished iiame. Fig. 3 is a similar view showing theparts in the position assumed when the lamp is extinguished. Fig. 4 is aview illustrating the application to the lamp of the cap for preventingevaporation and .providing for the filling of the fount. Fig. 5 is asectional plan view, partly in elevation; and Fig. 6 isa per-k spectiveview of the operating parts of the lamp. Figs. 5 and 6 are on a smallerscale than the other figures. V l

The' lamp-fount 1 is in the form of a segment of a sphere, a portion ofthe spherical casing being out away, so as to form an opening 2, boundedby a ange 3, which is formed by turning down the edges of the casing, asshown in Fig. 1, this inturned iiange 3 serving to confine a sheet 4 ofwire-gauze or perforated plate upon the top of a mass 5 of asbestosfiber or other absorbent material with Serial No. 687,443. (No model.)

which the lamp-forint is filled. The fount is contained within an outercasing 6, which has at the bottom an opening covered by a sheet '7 ofwire-gauze or perforated plate, said casing 6 being of so much greaterdiameter than the lamp-fount that a space is afforded between the twofor the circulation of air.

and for the reception of a swinging Iiame reducer and extinguisher, asdescribed hereinafter.

The casing of the lamp has hollow flanges fitting snugly to each otherand constituting a hollow rib 8, which may, if desired, serve as themeans-of supporting the lamp-casing upon the frame of a chating-dish orother structure in connection with which the lamp is intended to beused, this hollow rib also having bearings for a trunnion 9 at one sideof the lamp-fount and for a shaft 10, the inner end of which is seatedin a recess at the opposite side of the lamp-fount, said shaft 'carryingthe swinging flame reducer and extinguisher 1l, which likewiseconstitutes a segment of a sphere and is intended to fit as closely tothe casing of the lamp-fount l as is consistent with its free swingingmovement. The swinging segment 11 has a projecting arm 12, and a pin 13on this arm engages with a slot in one arm of a lever 14, which is piv;oted to the outer casing 6 and has another slotted arm engaging with apin 15, projecting from the lamp-fount, as shown in Fig. 5. Hence whenany movement is imparted to the shaft 10 tending to swing the segment 11upward or downward there will be a corresponding movement of thelamp-fount, the relative length of the arms of the lever 14 being such,by preference, that the extent of movement of the segment 11 is much ineX- cess of that of the lamp, so that the diminution of the Iiame, asshown in Fig. 2, or the extingtiishment of the flame, as shown in Fig.3, may be effected without tipping the fount to such an extent as toinvolve any risk of spilling the alcohol therefrom in case the absorb-1ent filling of the fount has been saturated to excess. In order topreserve the flame in a central position when the volume of the same hasbeen diminished, as shown in Fig. 2, the controller-segment 1l has an oening 16 formed therein, through which the ame passes when .means of ascrew-cap 19.

laps the body of the fount at the far side ofn the opening therein, asshown in Fig. 2.

In order to prevent the evaporation of alcohol from the lamp after thesame has been extinguished and the controller-segment has been restoredto its normal position, I use a plug 17, which iits snugly to the iiange3, bounding the opening in the top of the fount, and in order that thisplug may serve also as a means of measuring the proper charge of alcoholfor the lamp and of applying this charge of alcohol to the absorbentlling of the fount I make the plug hollow, perforate the bottom of thesame, as shownv in Fig. 4, and provide the top of the plug with anopening adapted to be hermetically closed by If, therefore, the hollowplug is filled with alcohol and the screw-cap is applied thereto, noneof the alcohol will escape from the perforated bottom Aof the plug,because no Opportunity is afforded for air to enter the plug above thealcohol therein; but if the cap 19 is removed the alcohol will flow intothe lamp-fount and will saturate the absorbent filling 'of the same. Therenewed application of the screw-cap then again closes the plug 17, soas to prevent any evaporation of alcohol from the fount.

Although I have described the lam p-fount as constituting a segment of a'sphere and although I prefer to adopt this form, it will be evidentthat the same may be cylindrical, if desired, the shape of thecontroller being likewise modified.

Having thus described my invention,Ik I claim and desire to secure byLetters Patent 1. An alcohol-lamp consisting of a fount of 4ocylindrical cross-section having an opening at the top and mounted so asto swing, with a curved controller-segment also mounted so as to swingon the same axis as the foun't, substantially as specied.

2. An alcohol-lamp in which are combined an outer casing, a lamp-fountmounted so as to swing therein, and a controller-segment mounted so asto swing between the lampfount and the casing, substantially as specified.

3. An alcohol-lamp in which are combined a fount mounted so as to swing,a swinging controlling-segment, and a connection between the two,whereby simultaneous movement of both by one operating device may beeected, substantially as specified.

4. An alcohol-lamp in which are combined a swinging fount, a swingingcontroller-segment having a projecting arm, and a lever having a fixedpivot and two arms one engaging with the fount and the other with theprojecting arm of the controllersegmen t, substantially as specified.

5. An alcohol-lamp in which are combined a lamp-fount having an openingfor the escape of the iiame, a hollow plug fitting snugly to saidopening and having a perforated bottom and an opening in the top, andmeans for hermetically closing said opening in the top of the plug,substantially as specified In testimony whereof I have signed my name tothis specification in the presence of two subscribing Witnesses.
